9 Claims. (Cl. 28-32) My present invention relates to the weaving art and more particularly to a novel construction of a warping frame.

The principal object of the present invention is to provide a warping frame which ,will greatly accelerate the winding of the warp.

Another object of the present invention is to provide a warping frame which will reduce unnecessary handling of the thread.

A further object of the present invention is to provide a warping frame having a single drive for the reel and the warp beam.

A further object of the present invention is to provide a warping frame which is simple in construction and easy and economical to manufacture and assemble.

.With the above and other objects and advantageous features in view, my invention consists of a novel arrangement of parts more freely disclosed in the detailed description following, in conjunction with the accompanying drawings, and more particularly defined in the appended claims.

In the drawings:

Fig. 1 is a perspective view of a warping frame embodying my invention.

Fig. 2 is a sectional view of one side of the warping beam drive.

Fig. 3 is a fragmentary view of the other side of the warping beam mounting.

In preparing the warp beam for a hand loom or any other type of loom it is customary to first wind the ends of thread on to a reel. The reel is then mounted adjacent the warp beam and the warp beam is then filled from the reel. This requires that the reel be driven during the reeling operation and that the warp beam be driven during the warping operation. The present invention provides a single frame and drive for both operations.

Referring more in detail to the drawings illustrating my invention, I provide a pair of spaced L-shaped supports having a journal bearing 11 adjacent the top of the vertical arm 12 of each support. A rotatable shaft 13 extends between the bearings 11 supported by the L-shaped supports. A reel 14 is mounted on a shaft 13 and is provided at each end with grooved wheel portions 15. The reel 14 is mounted for independent rotation on the shaft 13, but is provided with a lock bolt 16 for locking it to the shaft 13.

A table 17 is positioned between the L-shaped supports 10. The table 17 is rectangular in shape and its front legs 18 extend above the level of the table top as shown in Fig. 1. The table is also provided with an intermediate shelf 19. The front legs 18 act as a support for the warp beam mounting. The left leg of the table is provided adjacent the top with a supporting plate 20 for supporting one end of the shaft 21. Mounted on top of the other leg is a rectangular block 22 having its rear end pivoted as at 23 into the top of the leg. The forward end is provided with a narrow portion 24 having an opening for holding the right end of the shaft 21. A pin 25 having a manual handle is adapted to extend through the block 22 into the top of the leg to lock it into the position shown in Fig. 3. When it is desired to slide a warp beam on to the shaft 21 the pin 25 is lifted and the block 22 is pivoted into the dotted line position shown in Fig. 3.

The shaft 21 is provided at its outer left end with a drive pulley wheel 26. Further inwardly from the same Patented Apr. 5, 1955 end a drive plate 27 is keyed to the shaft and is provided with laterally extending pin 28. The warp beam 29 is provided at the left end 30 with an opening 31 into which the pin 28 slides. A second plate 32 is keyed to the right side of the shaft and is also provided with a pin 33 entering an opening into the right side of the warp beam. Thus the warp beam is held to rotate with the shaft 21 but is readily removable by disengaging the plate 32 and swinging the block. 22 into the dotted line position. Plate 32 and warp beam 29 can then be slipped off the shaft.

The single drive mechanism comprises a motor 34 which can be mounted on the floor between the left end of the table 17 and the left L-shaped support 10. A suitable reducing gear 35 is mounted on the table shelf 19 and is driven by a belt 36 from the motor 34. A shaft 37 extends from the gear 35 to the L-shaped support 10 which has a raised portion 38 for supporting the shaft. A pulley wheel 39 is mounted on the shaft 37 and is connected by suitable belting 40 to a pulley wheel 41 which is mounted on the reel shaft 13. A second pulley wheel 42 is also mounted on the shaft 37 and is connected by belting 43 to the pulley wheel 26 on the shaft 21.

In operation, when the-thread ends are being wound from the spools on to the reel 14, the bolt 16 is tightened and the motor 34 will drive the gear 35, shaft 37, and the shaft 13. To transfer the threads: from the reel 14 to the warp beam 29, the warp beam is locked to the shaft 21 as shown in Figs. 2 and 3. The bolt 16 is loosened so that the reel 14 is no longer rotated with the shaft 13. The motor drive will now drive the shaft 21 and the warp beam will pull the threads from the reel 14. The shaft 13 will continue to rotate but it will have no effect on the reel. During this stage of the winding, it is necessary to prevent the reel 14 from turning too rapidly and a suitable friction braking arrangement must be provided. As shown in Fig. l, a cord. or rope 44 is passed over each grooved wheel 15 on the reel 14. Each rope 44 is weighted, as at 45 at the back end and connected by a bar 46 at the front which is anchored to the table 17. The weight 45 frictionally holds the reel 14 against too rapid a rotation.

The above construction thus permits a single drive mechanism for both the reeling and. warping operations and reduces unnecessary handling of the reel or warp. The device is simple to set up and little time is lost between the reeling and warping.

Other advantages of the present invention will be readily apparent to a person skilled in the art.
